A pejorative term used to describe the southern region of New Hampshire (sometimes just the region of the state that is south of Manchester and east of Milford including the Merrimack Valley and Seacost) with the notion that it is turning into Massachusetts due to the large number of former Massachusetts residents moving there. The term denotes the idea that Massachusetts residents are causing NH taxes to be raised and a "nanny state" to be formed simply by being there. To much contrast, most Massachusians in NH are far right-wingers who come to NH as tax refugees.

A similar phenomenon would be "New Yorkticutt", the notion that the western part of Connecticut has been turned into a mini-New York city by moving there.

Person 1: New Hampshire?! More like MASSAHAMPSHIRE! With all of these Massachusetts people moving here we might as well let Massachusetts annex Rockingham and Hillsborough counties!

Person 2: Actually, the Massachusians are the only reason NH is still Republican, dumbass.
